Cancer expected to skyrocket in Asia

Smokeless tobacco is also a big problem in Asia's other giant, India, where many men and women chew some form of tobacco. Mouth cancer makes up half of all new cases in parts of the country.

A lack of vaccines that prevent cancer-causing viruses is another obstacle for Asia, which is home to about three-quarters of the world's liver cancers, caused largely by Hepatitis B infections.

A vaccine guarding against the virus has been available since the early 1980s and is routinely given to children in Western countries, but it is still not reaching large swaths of the Asia-Pacific.

Some experts worry it could take years before the new vaccine for the sexually transmitted human papillomavirus, or HPV, is available to women in developing countries. The three shots currently cost about $350 in the US and are 70 percent effective against preventing HPV, the main cause of cervical cancer. It is already the No. 2 cause of cancer among women in Asia, after breast cancer.

"The problem is so huge that it's very difficult for us to know where to start," said Dr. Franco Cavalli, president of the nonprofit International Union Against Cancer. "All the new cancer treatments are so expensive, that already in the affluent countries we are not able to pay for them. ... So imagine what that means for low-income countries where you have $20 a year per person for health expenditures."

Regular screening, such as Pap smears and mammograms, is too costly for many poor countries. Treatment with radiation or chemotherapy is unfathomable for most. And in Asia, many patients seek help from hospitals in the late stages of disease after traditional medicine has failed to cure them.

Monika Bardhan of Malaysia's NCI Cancer Hospital has seen a dramatic increase in cancer patients over the past four years. "It's staggering. Every day I see a patient with breast cancer - I just hold my own and say a prayer."
